Numerically modelled transport pathways in degrading permafrost

Andrew Frampton

A numerical model which couples heat and water conservation equations combined with a post-processing routine for particle tracking of water pathways is used to calculate travel times of solutes in degrading permafrost systems. The models are two-dimensional subsurface representations corresponding to 30 m depth and 100 m lateral extent. Modelling assumptions and details of the configurations are provided in the manuscript. The data set contains (i) spatially and temporally resolved subsurface water fluxes, (ii) spatially and temporally resolved subsurface phase saturations and temperatures, and (iii) subsurface pathway travel times.
